Had the same thought as Scouting. The detached units "In Support" need unique doctrines in the editor.
e.g. "Engage in combat only if attacked or if the unit you are supporting is attacked"
This would greatly help our artillery, who have cavalry unit in support but somehow keep on getting wiped out, while the supporting cavalry looks on with disdain. With this new doctrine our supporting unit would engage enemy cavalry before it wiped out the artillery. In a real battle, if a Commander sent a unit to support his artillery, that would become it's overriding concern.
A supporting unit has specific orders so although detached, the detached doctrine as it stands, does not really allow the unit to protect the artillery it is supporting.
Any chance this could be fixed?
